Increased Red Blood Cell Distribution Width (RDW) is linked to poorer pulmonary function, even after accounting for smoking. This suggests RDW may indicate unknown nutrient deficiencies affecting lung health.

Area of Science:

  • Pulmonary Medicine
  • Nutritional Science
  • Hematology

Background:

  • Pulmonary function is influenced by smoking and nutritional status.
  • Increased Red Blood Cell Distribution Width (RDW) is associated with nutritional deficiencies.

Purpose of the Study:

  • To investigate the hypothesis that RDW has an inverse relationship with pulmonary function.

Main Methods:

  • A cross-sectional study of 1,616 healthy adults aged 35-79.
  • Assessed pulmonary function (FEV1, FVC) and related factors including RDW, smoking history, and nutrient levels.

Main Results:

  • Found a direct relationship between RDW and smoking pack-years/status.
  • Confirmed an inverse relationship between FEV1/FVC and RDW, independent of smoking.

  • RDW and antioxidant vitamin levels explained significant variability in FEV1.

    • Conclusions:

    • Confirmed the hypothesis: RDW is inversely related to pulmonary function.
    • Suggests RDW may serve as a biomarker for unidentified nutrients impacting lung health.
